Most people know that junk food can damage your health, but fewer realize that some everyday drinks, often seen as harmless, can also stress and damage the kidneys.
According to Global Facts: About Kidney Disease, chronic kidney disease (CKD) affects approximately 10% of the global population, leading to over 1 million deaths annually due to a lack of access to affordable treatment.
Research in the American Journal of Clinical Nutrition has linked one effective strategy to protect your kidneys: eliminating certain beverages from your diet.
Understanding how to prevent further kidney damage involves making informed choices about what you consume.
1. Sugary Sodas and Carbonated Drinks
Regular consumption of sugary sodas and carbonated drinks has been linked to an increased risk of CKD. These beverages are high in added sugars and phosphoric acid, which can strain kidney function over time.
A study published in the Clinical Journal of the American Society of Nephrology found that people who consumed two or more sugary sodas daily had a higher risk of developing kidney disease.
Go for water, herbal teas, or naturally flavored water with lemon or cucumber to stay hydrated without compromising kidney health.

2. Processed Fruit Juices
Fruit juice can affect kidney health in both helpful and harmful ways. Some juices provide hydration and essential vitamins, but others are packed with sugar and potassium, which may be risky for people with kidney problems.
Although 100% fruit juice is often marketed as a healthy option, it may not be safe for those with kidney disease.
Many juices contain over 200 mg of potassium per serving, which can be too much for renal patients.
A study in the Journal of Renal Nutrition highlighted this concern, calling fruit juice a “grey area” for people managing kidney health.
Store-bought juices can also be high in added sugars and preservatives, which add stress to the kidneys. The National Kidney Foundation recommends choosing unsweetened juices with no added sugar.
Unsweetened cranberry juice is often a better choice, as it has less sodium and potassium compared to options like grape or apple juice.
Choose whole fruits over juices to benefit from fiber and natural nutrients without the added sugars.

3. Diet Sodas
Diet sodas, though low in calories, contain artificial sweeteners that may negatively impact kidney health.
A study in the Clinical Journal of the American Society of Nephrology found that people who consumed two or more artificially sweetened sodas daily were twice as likely to experience a decline in kidney function compared to those who avoided these beverages.
Replace diet sodas with sparkling water or unsweetened iced teas to reduce artificial sweetener intake.

4. Alcoholic Beverages
Drinking too much alcohol is widely known to raise blood pressure and increase the risk of liver and kidney damage.
Alcohol can dehydrate the body and put extra strain on the kidneys, especially when consumed frequently or in large amounts.
For people with kidney disease, the recommended alcohol limit is the same as for the general public: no more than 14 units per week for both men and women.
According to the Journal of Substance Abuse, explains that because alcoholic drinks vary in strength and size, so using units is a more accurate way to measure intake. One drink doesn’t always equal one unit.
According to NHS guidelines, 14 units is about six pints of regular beer or 10 small glasses of lower-strength wine.
If you drink up to 14 units a week, it’s safer to spread them over three or more days. Binge drinking, even just once or twice a week, can increase the risk of long-term health issues and serious injuries.
Limit alcohol intake to moderate levels and ensure adequate water consumption to maintain kidney function.

5. Energy Drinks
Many people turn to energy drinks for a quick boost in alertness and stamina. However, that surge of energy can come at a serious cost to your kidneys.
These drinks often contain high levels of caffeine, sugar, and synthetic additives that can stress the kidneys over time.
The National Kidney Foundation warns that energy drinks are considered ultra-processed foods (UPFs).
Studies have linked high consumption of UPFs to a greater risk of developing kidney disease. Energy drinks fit into this category due to their heavy load of caffeine, added sugars, and additives like phosphorus and sodium.
Caffeine, in particular, is a major concern. It acts as a diuretic and can lead to dehydration. When your body is dehydrated, blood flow to the kidneys drops, which may impair kidney function, especially if energy drinks are consumed regularly.
Choose natural energy boosters like green tea or a balanced diet rich in whole grains and proteins.

Signs of Kidney Disease
In its early stages, kidney disease often shows few or no clear symptoms. According to the NHS, it’s usually discovered during routine blood or urine tests done for other health concerns.
Detecting kidney disease early can make a big difference. With the right medication and regular monitoring, it’s often possible to slow down its progression.
As the condition advances to later stages or leads to kidney failure, more noticeable symptoms may appear, such as:
- Headaches
- Trouble sleeping
- Persistent itching
- Feeling short of breath
- Nausea or feeling sick
- Erectile dysfunction in men
- Constant tiredness or fatigue
- Blood in the urine
- Frequent urination, especially at night
- Muscle cramps
- Unexplained weight loss and reduced appetite
- Swelling in the ankles, feet, or hands due to fluid buildup (oedema)

When to Seek Medical Attention
If you experience symptoms such as persistent fatigue, swelling in the legs or ankles, changes in urination patterns, or blood in the urine, it’s essential to consult a healthcare provider promptly. Early detection and management can prevent further kidney damage.
What to Expect at the Doctor’s Office
During a medical consultation, your healthcare provider may:
- Review your medical history and lifestyle habits
- Perform a physical examination
- Order blood tests to assess kidney function (e.g., serum creatinine, glomerular filtration rate)
- Conduct urine tests to check for protein or blood
- Recommend imaging studies like ultrasound if necessary
Based on the findings, your doctor will discuss appropriate treatment options and lifestyle modifications to protect your kidney health.
